(GRANTED UNDER THE PROVISIONS'OF THE ACT OF MARCH 3, 1921, 41 STAT. 1.,1813.)

To all whom it may concern Be it known that I, ARTHUR Dn CoNINoK, asubject of the King of Belgium,residing at 43* Rue des Aduatiques,Brussels, Belgium, have invented new and useful Improvements in orRelatin to Braking Systems, (for which I have led applications inGermany, October 21, 1918, Patent No. 334,175;Bel-

1918, Patent No. 273,977; France, January 28, 1919, Patent No. 495,244,and Great Britain, February 13, 1919, Patent N 0. 136,132.)

The many advantages of simultaneously braking the driving and steeringwheels of an automobile vehicle are known.

The devices hitherto suggested with this end in view are generallycomplicated, costly, awkward to adjust and difiicult to apply. Moreoverthe braking effort is usually balanced by means of a special Whippletreeor ,similar mechanism for both the wheels of each axle.

The present invention consists in proproviding an arrangement enablingdiagonal balanced braking to be obtained by means of flexiblebrake gear.the adjustment of which is easy and instantaneous.

One constructional form of this device is shown diagrammatically in theaccompanyin; drawing merely by way of illustration.

Figure 1 is an elevation, and

Figure 2 a plan showing the arrangement of the brake rigging and the wayin which 7 it is actuated and compensates or balances the brakes bymeans of a single controlling member.

Figures 3 and 4 show respectively a side view and an end view of theadjustable device for attaching the cable of the brake gear to the leverthat actuates the brake blocks or segments.

The two flexiblediagonalbrake gears consist of two metallic cables 10and 11 the extremities of which are respectively attached to one of thelevers 12 of the brake of one of the front wheels and to the lever 13 ofthe brake of the back wheel situated on" the opposite side. I

Each cable 10 and 11 passes inside a hollow shaft 14, which is mountedtransversely to the underframe in bearings 49 and is provided at itsextremities with two diametral arms 15 and 16, each terminating in aguid- .axle of the vehicle.

ing spoon 17 or similar device for the purpose of deflecting the cablesparallel to the diagonalbrake rigging which brakes the four wheels ofthe vehicle simultaneously.

It will be seen from Figures 1 and 2 that the effort exerted on eachcable by the arms 15 and 16 of the swingle-tree shaft 14: is balanced bythe sliding of this cable inside the said shaft and on the guidingspoons 17 of these arms.

The extremities of each cable are attached to the corresponding brakelevers by means of the device shown in Figures 3 and 4.

The extremity of a cable is threaded through a tube 19 that screws intoa nut 20 which is supported by lateral trunnions 21 in the apertures 22of a fork 23 terminating each of the brake levers 12 or 13.

The cable terminates in a soldered knot 24 in the form of a sphere whichbears in a corresponding groove in the extremity of the tube 19.

A thick washer 25 is inserted between the pivoting nut 20 and two locknuts 26.

The adjustment of the brake rigging may in this way be effected at eachextremity'of the cable by suitably screwing the tube 19 into the nut 20and then tightening the lock nuts 26.

The screwing of the tube 19 is efiected by means of a spanner or keyacting on the square part 27 of the tube.

Owing to the knot extremity 24 of the cable being spherical the tube 19can be screwed up or unscrewed without causing torsion of the cable.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed. I declare thatwhat I claim is 1. An adjustable balanced braking System actingdiagonally on the four wheels of a vehicle, comprising four brakelevers, two flexible connectors uniting said levers in pairs diagonally,a common. hollow shaft mounted transversely to the underframe andthrough which said connectors slide, bearings for said shaft, a leverfor said shaft to enable the same to be turned, and diametri-Speeification of Letters Patent.
